Description

one

The invention relates to the field of hydraulic engineering and can be used for sumping organic-mineral soils, such as peat, cyclopel, silt, containing rhizomes of vegetation.

From auth. St. L1 355349 A rotary bucket group collecting device is known, which is used as replacement equipment in the dredger. This device is made in the form of a rotor with buckets, a cylindrical bunker and a suction pipe. In order to increase the efficiency of grinding ground containing vegetable inclusions, the cylindrical bunker is made in the form of a grid made up of knives.

However, in this device, the water transporting the developed soil enters the suction pipe and through buckets that are not involved in the excavation of the soil, which significantly reduces the consistency of the pulp.

The aim of the invention is to increase the pulp consistency.

This is achieved by the fact that the bucket rotor is equipped with

attached to the blades with a screen installed in the cylindrical part of the bunker, and a mechanism for fixing it in two positions, consisting of a clamp located on the flange of the suction pipe and latch with carrier mounted on the bunker, which form the engagement of the bunker with the rotor, and on the flange of the bunker are made openings for insertion of retainers into them, as well as in that the retainer is made with a slot for inserting a latch thereto.

FIG. 1 shows the proposed device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 2: in Fig. 5, a scheme of excavating the soil with the proposed device, in case of a fan displacement of the dredger in position a and b. The bucket rotor bucket device includes a rotor with felts 1, a hopper 2, the cylindrical part of which is a grid made up of knives

3, the suction pipe 4.

The blades 5 are reinforced on the surface of the rotor. Inside the cylindrical part of the bunker is mounted a screen 6, on its flange

7 - a latch 8 on the axis 9 with a spring 10. Cases 12 and 13 are attached to the flange 11 mounted on the suction pipe 4, into which are placed the long 14 and short 15 clamps, held in the initial position by the springs 16. The long clamp 14 alternately in in the holes 17 and 18 on the flange 7 of the screen 6, provides coordination screen 6 relative to the suction pipe 4. Long 14 and 15 short clamps have a groove with bevels. By means of a groove and a spring 10, the latch 8 rotates about an axis 9. The guides 19 mounted on the flange I are provided with clamps 20, which hold the hopper 2 from axial displacement. The carrier is fixed on the rotor 1. The locking pins 14 and 15 are connected with the mechanism that performs their reciprocating motion in the housings 12 and 13.

When the samsnar is moved at a predetermined angle relative to the stationary stern, the bunker 2 with the screen 6 is rotated alternately in the extreme positions with the screen 6 in a position that prevents water from entering through buckets that are not involved in the excavation of the soil.

Works rotary-bucket device as follows. At the end of the working stroke, for example when moving the device from right to left (see Fig. 5a), the reciprocating movement of the long latch 14 is removed from the hole 18, while the long latch 15 simultaneously overcomes the resistance of the spring 10 and engages the latch tooth 8 with the planet carrier 21 of the rotating rotor 1, and at the initial moment the latch 8 in engagement with the planet carrier 21 holds the cylindrical surface of the retainer and then the cylindrical surface of the screen 6, as a result of which the hopper 2 with the screen 6 starts rotates with the rotor 1 until the opening 17 iie is set against the long latch 14. The latch 14 falls under the action of the spring 16 into the hole 17. The latch slot sets against the latch 8 that has moved here and the last force of the spring 10 is buried into the long latch slot 14, and the latch tooth 8 disengages from the planet carrier 21 and the hopper 2 with the screen 6 stops at the position where the wall of the slab is to the right and the screen 6 will prevent water from flowing through the buckets to the left, as shown in FIG. 56.

In the extreme right position, the mechanism of the reciprocating movement of the long latch 14 is removed from the hole 17 and at the same time overcomes the resistance of the spring 10 and engages the latch tooth with the carrier 21. The hopper 2 with the screen 6 rotates until the hole 18 is installed against the long latch 14, and the latch 8, mounted on the flange 7 of the screen 6, against the short latch 15. The long latch 14 by the force of the spring 16 falls into the hole 18, at the same time the latch 8 under the influence of the spring 10 occupies a position in the groove short latch 15, returned to its original position by the spring 16 immediately after turning off the mechanism of returning the reciprocating motion, and the latch tooth 8 is disengaged from the carrier 21. The hopper 2 with the screen 6 stops at the position when the wall of the slab is on the left, and the screen 6 will prevent water from flowing through the buckets on the right. Then the cycle repeats.
